1000 hp NA from a straight-4? I'm not one to say it can't be done, but that is a very steep goal, especially for a 4-banger. Heck, it'd be hard to get a V8 that high NA without using every trick in the book and race-grade parts.

It would be an interesting and impressive exercise if someone pulled it off, but seriously, how reliable would that even be, even in a limited-run vehicle? I personally don't see anyone, even Honda, attempting such a feat, since it's not useable on the street, and really not practical period.

The only way I could see such a thing being pulled off in the near future is if Toyota (for example) decided to put together a drag Prius or something, with a high-hp 4 augmented by an electric assist of about equal power.

I don't know, can it be like a 5 litre 4 cylinder?

haha 5 litre may be much. i'd be odd to see , but would be impressive if could be done. Maybe a NSX motor stroked to a 4 litre , 16 compression fully built. Probably still wouldn't hit close to 500whp

Theres a guy on here that's running an F20C for his Bonnieville salt flats car. I'll have to look around but I do believe he's got the fastest "Honda."

HvRRZ

ya didn't he hit 250 mph or something like that????

Kel

Yea, something like that, I'm trying to find the post he made on it but you know how the search function on here works.

There's a guy on here I think his username is Greenlight or something like that. Anyway, he had the f20c rev to 12,000 rpm or something like that. I presume that's the most powerful NA f20c

LUV2REV

Most powerful or highest revving ?? Unless he has invested a small fortune in building the motor I doubt he is making much more power at 12,000 RPM.

steven975

if he can make just 150lb-ft at that RPM he would have 350HP.

there is that kid with the 2.5l stoker f20c..s2k @18 or something.
